New Piston finished

After many stops and starts, successes and failures, I have a functioning piston.





The results are great, especially after I stopped using a Pavoni-style preinfusion and changed to a ~2 second ramp up to full pressure. I'm getting more and more pleasant flavors out of the Yunnan beans, but I'm looking forward to two Italian-style espresso blends which I'll be getting from Arabica Roasters (in Beijing) soon.

I know, this is old stuff, but can you post a parts list/source/mods for the New Piston? I am getting a Presso and I expect to follow in your footsteps. Thanks, DT

Hi

Can you let me know what additional benefit/advantage you get after modifying your Presso in the manner you have?

I am very interested.

Thanks!

I second. I know this is old, but I would like an email or post of parts list because my presso has started gushing water. I have tried to replace the o-ring from a hardware store but cannot get the right fit and have no possible way of knowing how to fix this because I am not technical. Please, my presso will not work now and I need help fixing. Email me, I am fine with that. My email is parkerto@gmail.com
